UNITED STATS MONROE HUDGENS. OF COOKVILLE, TENNESSEE.

CULTIVATOR STRUCTURE.

Application filed December 14, 1921.

T0 all whom t may concern:

Be it known that l, Mormon HUDGENS, a citizen of the United States, residing at Cookville, in the county of Putnam and State of Tennessee, have invented new and useful Improvements in Cultivator Structures, of which the following is a specification.

My present invention is designed more particularly as an improvement on the con struc-tion disclosed in my contemporary application filed June 15, 1920, Serial No. 389,169.

The general object of the present invention is the provision of an improved and highly eiiicient cultivatork construction.

To the attainment of the foreging, the invention consists in the improvement as hereinafter described and definitely claimed.

In the accompanying drawings, forming part of this specification Figure 1 is a view showing a wheeled structure embodying my invention with the near ground wheel omitted and the spindle therefor in section.

Figure 2 is a plan view showing said structure complete.

FigureV 3 is a detail front elevation with parts in transverse section. l

Figure 4 is a detail side elevation of one of my novel planter units.

Similar numerals designate corresponding parts in all of the views of the drawings.

The wheeled structure illustrated comprises a main frame 1, an axle 2 and ground wheels 3. The main frame 1 is of general U-shape in plan, with the bight of the loop foremost and the ends thereof connected to the axle, it being understood in this connection that the main frame is arranged forward of the axle. The said main frame 1 includes upper and lower bars 4, Figures 1 and 3, bolts 5 connecting the same, and tubular sections 6 mounted von the bolts 5 and interposed between the bars 4 and having for their function to brace the bars and to maintain the saine in spaced relation. The axle 2 includes a horizontal intermediate portion, pendent portions integral with the ends of the intermediate portion and spindles extending outwardly from the said pendent portions, the ground wheels 3 being mounted on the said spindles in the ordinary well known manner.

The' structure also includes a tongue 7, and a double-tree 8 connected to the tongue Serial No. 522,270.

in front of the main frame 1. At an intermediate point of its length the tongue is pivotally connected to the forward portion of the main frame 1, a clip 10 being disposed over the tongue and a pivot bolt 11 being extended throughthe clip 10, the tongue 7 and the forward portion of the main frame 1. The rear end of the tongue 7 is equipped with a rearwardly extending metallic bar 12, Figure 2, which is adapted to play between two transverse straps 13 that are fixed to the main frame 1 and constitute a race for thel bar 12 when the rear portion of the tongue is moved in either direction.

At 15 is a drivers seat, and at 16 the support therefor, said support being connected at 15x to the axle 2, and at 16", Figure 1, to the forward portion of the frame 1.

Appropriately fixed with respect to and arranged transversely of the forward portion of the main frame 1 is a tubular member 3l. The said transverse tubular member 31 preferably extends between the bars 4 of the main frame, and is disposed and held in shackles 32, each of which has its arms connected to the frame 1 through the medium of a bolt 33 that extends through the upper and lower bars 4 and the arms of the shackles as shown. Telescopically journaled in the tubular member 31, and detachably retained by keys 34 are inwardly-directed arms 34X on beams 25a, there being one beam 25a to each of the planter units, andeach key 34 being movable in an arcuate slot 34e in the transverse member At 37 is an arch member for unitholding and spacing purposes. The said arch member is provided with end portions 37X in each of which is a plurality of aper tures for adjustment purposes, and on each of which is an upstanding rod 38X which carries a spring 38.

The structure also includes levers 39 for the raising and lowering and adjustable fixing of the arch 37. The said levers shown as hand levers extend upwardly from the rear portions 1x of the frame 1, and their lower portions 39X extend forwardly to the rods 33x to whichthey are connected.

Each of the before mentioned beams 25a' is fixed to or integral with a sub-beam 25h extending rearwardly from the lower end of the beam 25a. `Said sub-beam 251 is conneted at 25 to one end portion 0f the arch wardly from the points of connection and having on their rear portions ground-working devices and also having arms at their forward ends, connections between said arms and said draft means, levers on the trailing beams and having arms, rods connected to said arms and extending loosely through the beams carrying the groundworking device, springs on said rods between said beams and the lever arms, and means to adjustably EX said levers with respect to said t y'ailing beams.

3. A unit for use on wheeled agricultural apparatus, comprising a pendent beam for connection to the frame of such apparatus, a trailing beam carried by and extending rearwardly from said pendent beam, a beam pivotally connected to said trailing beam and extending rearwardly and downwardly from said point of connection and having a ground working device on its rear portion and an arm at its forward end, a lever on the trailing beam, means to adjustably fix said lever with respect to said beam, a rod connected with the lever and extending through the beam carrying the ground working device, and a spring on said rod and between said beam and said lever.

l. The combination in an agricultural apparatus of a wheeled frame, draft means connected with said frame, trailing beams connected with said frame, beams pivotally Connected with the trailing beams and eX- tending rearwardly and downwardly from said points of connection and equipped on their rear portions with ground-worling dev'ces and having at their forward ends arms, and Connections intermediate said arms of said beams and the said draft means.

The combination in an agricultural ap paratus of a wheeled frame, draft means connected with said frame, trailing beams connected with said frame, beams pivotally connected with the trailing beams and eX- tending rearwardly and downwardly from said points of connections and equipped on their rear portions with ground working devices and l'raving at their forward ends arms, and connections intermediate said arms of said beams and the said draft means; the said trailing beams being equipped with levers and means to adjustably fix said levers with respect to said beams, and yielding means being interposed between the beams carrying the ground working devices and the said levers.

In testimony whereof I affix my signature.
